Total Home Comfort, Delivered with Precision

MOST RECENT June 2026:
Weltman has been purchased by Princeton Air. They have been really great. A seamless transition on the customer side. Eric was just here to put in a new anti-scaling system and a pressure relief valve for the house. Very happy!

UPDATE:
Now in our home for almost 8 years and Weltman has never disappointed! Chris L came today and was completely professional and quick for our yearly inspection of our furnace before the cold winter! It’s great to know they keep great notes and, almost, know more about our system than we do!

Weltman will always make it right if something is wrong. They will also get to you ASAP! We have been customers since we bought our home 3 years ago and have been completely satisfied!

We have used Princeton Air twice for our HVAC and once for plumbing. Each time, the technician was courteous and professional, and the issues were resolved. We recommend Princeton Air!

Teck was knowledgeable and courteous

The technician Alfredo is great

I was recommended Princeton Air by a friend and I’m very happy that I was. I had a hvac and furnace system that was 25 years old and in dire need of replacement.
Chris from the company came out very promptly and did a full review, taking the time to take me through the different options. From there we reached an agreement and within one week the team came out and did a full dual zone system replacement.
I was blown away by the professionalism and indeed sheer hard work of the installation team. They arrived at 08.30am and finished at 8.30pm working tirelessly to complete the job in one day. A huge thank you to Princeton air, Chris and the install team -Jorge Vizueta, John Jaramillo, Juan Torres and Jhonny Anacona for a really cool air conditioning experience. Thank you!

The repair man, Dominic came out this morning to inspect our AC system. He was extremely knowledgeable, incredibly kind, and explained things very well. I work in construction and can tell you that Dominic is one of the best I’ve seen in years. Princeton air is very lucky to have him as an employee as he is SUCH AN ASSET to your company.

I also want to give a special thanks to Leah the customer service representative I spoke to. Also extremely kind and helpful. I have had the worst two weeks of my life and two strangers taking the time to kind made my heart smile. Thanks again Leah and Dominic.

Wilver did a great job replacing my toilet. He was respectful and quickly diagnosed the problem. He came back with a beautiful Glacier toilet which he quickly installed. I highly recommend him for any toilet job!

I just had Alberto fix my furnace as my house was 60 degrees this morning…he diagnosed the issue quickly, got the part and installed it in record time! He was my angel of the hour and I will never forget all he did for me today. I highly recommend him if you have a heating issue.

I had Brian replace my electrical box and he did a fabulous job. I highly recommend him if u need it done.

Jose just fixed my AC problem as it was not coming on and a heat wave is coming this week! He was extremely knowledgeable, went outside to check everything (thorough) and got my cool air on expeditiously! He has a wonderful demeanor and a pleasure to work with. I highly recommend him for any of your AC needs this summer. Ask for him…you'll be happy you did!

Norman was great!!! He has come before. His advice and work were great!!!! Unfortunately Princeton Air, formerly a family run business, has been bought by a large corporate group, and we have chosen not to use them any longer

The technician was thorough, knowledgeable and professional. He also called for an ETA and was punctual.

I wanted to say a BIG Thank you to Princeton Air and Jesus C for coming to our rescue when AC in our house wasn’t working (despite it working fine 3 weeks ago). My daughter and her friends arrived on Friday afternoon for a girls weekend. Even though the compressor unit outside was running, no air was coming through the vents inside the house. After talking her through a few things over the phone (none of which resolved the issue), I called Princeton Air.
Despite it being already 5pm on Friday, they dispatched a technician who arrived within an hour. Jesus C called me several times to keep me updated about the repair. Within 45 min, the air was blowing COLD!!
I highly recommend this company. I am beyond grateful for the prompt and professional service we received.

Thanks so much for the EXCELLENT service from Norman. He was very knowledgeable and so friendly. Really nice guy. Thank you Norman and thank you Princeton Air.

Just to let you know everything here is fine. Norman was wonderful!! Helpful and very friendly. Thank you Norman and thank you Princeton Air.

Great service , Ryan was fantastic

We recently had a new AC unit installed by Princeton Air and had a great experience from start to finish. The installation went smoothly, the team was professional, knowledgeable, and respectful of our home, and we are very satisfied with the quality of the work.
We did have one minor issue after the installation, but Dominic McGinley responded quickly and took care of it right away. His prompt service and commitment to making sure everything was working properly really stood out.
Overall, we’re very happy with Princeton Air and would highly recommend them to anyone looking for HVAC services.

Excellent technician with thorough explanation of the problem

Dillion was very pleasant ,He informed me what he was going to do what Needed to be done and afterwards Everything that was completed

Jorhe arrived and listened to what I needed in this routine service call and when he finished all my questions were answered & for the 1st time I’m able to understand the function and area each thermostat controls!
Cheers for you Jorhe!

Replaced central a/c system. Team arrived early morning and explained the process thoroughly, asked if we had any questions, then proceeded with the work. The job was completed quickly, a couple of little glitches were resolved with no impact. Only concern I had, we did not receive a call the day before confirming installation and time. All in all I would still recommend Princeton Air.

Great job. Worked efficiently. Work area clean

Thank you for AC inspect and helping me make decision to replace old system and answering my many questions . Looking forward to new AC. Thank You!!!

Jimmy and Kionah were absolute professionals! Timely, well mannered, thorough with all tasks! They installed all parts of the system with skill and focus, while answering any questions we had. K actually swept my stairs after they were done. I had plumbers the day before, trust me they did NOT do that. I was cleaning for an hour after they left. But Jimmy and K, they left my house as clean as they found it and at a perfect

Prompt and very knowledgeable

We have heating and air program. Technician was very efficient and friendly.

We had some issues with our electricity. Princeton Air responded promptly with a same day appointment and James took care of it in a professional manner.

Norman was pleasant and friendly and professional. He was thorough and completed the check up quickly, too.
